Fun isn't it. Personally though I am still only adept at creating collapsing spaghetti.I think this is similar fun, I got it from a link of IAmEric's; freaky orbits under gravity.After seeing Soda I was wondering whether something similar could be created as a silly finance toy (on Wilmott?) ? A market with only a few simple securities and the ability to create arbitrary trading algorithms from simple rules. Maybe we could finally lay to rest the question of whether TA works or not .
